Product Details

Generac Guardian 11kW With Whole House Switch Generator - 6438

Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage. Has the ability to backup a 3-ton air conditioner, well pump or water heater, and the main rooms of your house.

Features:

  • Generac OHVI® Engine
    Your Guardian Series generator might have to get you through days—or weeks—without utility power. Its OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.
  • Evolution™ Controller
    The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.
  • Certified for 18" Installation to the Home
    Third-party certified to NFPA standards to be installed as close as 18” from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes.
  • Easy Installation
    With an intelligent pre-wired transfer switch, re-engineered connection points, and composite mounting pad that eliminates the need for a poured concrete base (unless specified by local codes), the Guardian Series 11  kW generator is easy to install.
    Rated for Operation in Areas with Low Natural Gas Pressure
    In areas with low natural gas pressure, the Guardian Series 11 kW generator can operate on natural gas pressures of only 3.5” of water column.
  • All-Weather Steel Enclosure
    Our durable powder-coat finish helps make the sturdy, Galvanneal steel enclosure perfect for all weather confitions. It’s also able to withstand 150 mph winds.
  • Tool-less Fuel Conversion
    Switch between natural gas and LP fuel in the field in a few seconds, without the need for any tools.

A generous neighbor helped us get through multi-day power outages two winters in a row by loaning us an old, cranky portable generator. We did not have option of finding other shelter because my wife's poor health and dietary restrictions keep her homebound. I took the second outage as a clear sign we needed our own generator. I chose a Generac Guardian and an automatic transfer switch for its simplicity and the ability to power our whole house (not just the boiler, freezer and some lights on extension cords). Although there were no power outages during the past two winters, I still feel the Guardian is best home improvement we've ever made because it gives us the security of knowing we'll get through upcoming winters (and other events). This week's automatic Guardian 12-minute test run prompted me to write this review. -- Ward in rural Massachusetts

Had this product installed in August of 2013 and have had constant problems: 1) Oil leak and battery acid leak upon initial installation. Generac agreed to replace. 2) One month later new generator installed and fuse was blown upon installation 3) One week after new generator installed the transfer switch broke. All power to my house turned off 4) One week later I had a problem with the controller which shut down the unit. I have had the unit installed and in service for probably less than four weeks and have had to deal with five different part failures. Generac has been good about dealing with the problems but the overiding fact is that this product is very unreliable. For a product that is used in an emergency, this should be unacceptable. I would strongly advise anyone thinking of purchasing to look elsewhere.

Very happy with my new Generac!

By 

from Whiting

Comments about Generac Guardian 11kW With Whole House Switch Generator:

I purchased the Generac Guardian 11kW whole house generator with one power management module, and a whole house switch. I love it! The power's gone out several times since the install, and it has had the lights on in ten seconds flat every time! Amazing! It's quiet, attractive, and so far very reliable.

It's there when you need it

By 

from Freeport

Comments about Generac Guardian 11kW With Whole House Switch Generator:

After installing our Generac 11 KW in late August this year, we had a power outage at 5:30 am on a cold, windy, and rainy morning in September. Within seconds, we could hear the generator start and the transfer switch click as it put our house on backup power. Excited, I ran around the house checking lights, the furnace, the well pump, and those things that you need to get to work first thing in the day. All were working perfectly, and we had no delays in getting up, showered and ready for work. I made it to work at my usual time, and quickly spread the word of how nice it is to have my new Generac whole house generator ready when you need it. No gas cans to fill, no dragging out the portable in the rain and getting it hooked up to the house. And it is QUIET.. It has already proven to be a Godsend!

So in love with my generac

By 

from Summersville

Comments about Generac Guardian 11kW With Whole House Switch Generator:

I have 5 small children so we needed a generator that is simple to use and durable. The first time our power went out and 3 seconds later our whole house was with electric again, I fell in love! It's a real blessing to have a generator so I know my kids won't be cold or hungry from the food spoiling in our fridge! And it's a real plus that they will still be entertained with their tvs and game systems lol I could go on for days about the benefits of having a generac! I wish I would have had it when a huge derricho hit us and we went without power for over 2 weeks! That was one of the hardest times of my life! We lost all our food and it was so cold! I'm so thankful I don't have to worry about that happening again!!

Great product...peace of mind.

By 

from Plainview

Comments about Generac Guardian 11kW With Whole House Switch Generator:

After two major storms in our area over two years, plus many minor outages on our area over decades, we finally invested in a Generac. While we are actually in progress of getting the transfer switch replaced (under warranty), we've been very happy with it and can now rest knowing we will be covered in any future storms.

This product is what we've been looking for in a Generator.

By 

from Canton

Comments about Generac Guardian 11kW With Whole House Switch Generator:

Before purchasing this product we did some research, but found Generac was the one for us. The staff was very knowledgable, courteous and answered all of our questions. On the day of installation Jason, Charlie and Exavier were on time, installation was very quick, as everyone knew exactly what they were doing. The day of the weekly test, it performed beautifully. This gives us such peace of mind. We would highly recommend you to anyone we know that wants a generator.

This generator is perfect for a rural home.

By 

from Pine Bush

Comments about Generac Guardian 11kW With Whole House Switch Generator:

We lived in our home that we built 20 years ago... for 20 winters... and several power outages... and worried about frozen pipes and heat and water unavailability each season. I finally decided the purchase of a Generac generator (11 KW) would be WELL worth it! The unit looks great, is quiet, was installed very professionally, and I CAN SLEEP at night in the winter!! Anyone who lives in a rural setting, who experiences occasional power outages, would be much happier if they invested in one of these units. The piece of mind is priceless.
